IPTV disappears

Hello I am using version: 10.5.5
I add the channels in m3u format, but the channels disappear every 2 or 3 days and I have to re-scan, any suggestion or something wrong? Thank you

That’s… strange. I haven’t noticed that. Are you adding it as an M3U tuner in the regular Live TV section, or using the IPTV plugin?
